These photos are believed to have been taken in October of 1978 at an apparent Star Wars promotional event that took place inside the Showroom. Star Wars was originally released on May 25, 1977. Photos by Thomas Berry.
Here we see the Showroom in 1983 (on left) from Style & Vernacular - A Guide to the Architecture of Lane County, Oregon (1983 Western Imprints) and in 2003 (on right) from Eugene Modernism 1935-1965.

Note: The lower half of the Showroom's floor to ceiling glass windows have been covered with plywood to protect against vandalism. The Showroom is waiting for us to breathe new life into it!
